Nulling Local Strings?

[Darthfett]

In the past, I read that local strings needed to be nulled like so:

local string str = "asdf"
set str = ""

However, recently I rarely see anyone null strings. They null everything local except for strings, reals, integers, and booleans. However, I am starting to become unsure about whether I should be nulling them, or if I should just leave them without setting them to "" after the function.

Could someone please clarify?

Thanks in advanced!

i remember seeing some thread about it saying that they don't have to be nulled (thought i might be mixing up but i pretty sure about this one)

You don't have to null them or set them to empty string ("").
